Application iled April 7, 1914. Seria1No.`830,207.

To all whom t may concern:

Be it known that we, FREDERICK C. OVER- BURY and HOWARD CARLETON PLA'rTs, citizens of the United States, and residents, respectively, of New York, in the county of New York and State of New York, and of Rutherford, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Weatherproof Coverings, (Case 13,) of which the following is a specification.

This invention vhas for its object to lprovide a waterproof covering for roofs and side walls which will produce an ornamental effect, and at the same time effectively prevent leaks.

0n the accompanying drawings, Figure l illustrates a Section through a section of a roof embodying the invention. Fig. 2 represents a perspective view of a portion of the saine;r F ig. 3 illustrates a different einbodi- Fig. 4 represents still 'another embodiment of the invention.

. Figffshows conventionally a magnified section ghy a `portion of the covering.

ring consists of flexible prepared the ma ket'inay be utilized. In general, the covering,ciisistsof a sheet, strip or blank of wool felt, paper, cloth, or other absorbent material, having the proper strength, saturated or impregnated with a waterproofing compound, preferably. a hydrocarbon such as soft pitch, asphaltum or any -like waterproofing material, and coated on one oi' both sides with a coating or facing of weatherproof pitch or bitumen, such as a liigh-inelting-point steal-in pitch, as'phaltum or a mixture of pitch and asphaltum. Preferably the saturating compound has a relatively lowl melting point, so that 'it will remain comparatively soft, whereas the coating or facing compound has a relatively high melting point so that it will not become' unduly softened when subjected to solar heat in warm climates. The saturating and coating compounds are preferably applied while in a soft and plastic condition, being either molten or dissolved with a suitable volatile solvent, so that, when the completed blank is cooled or dried, the coatings will set or harden.

made by any of the approved his water andweather proof- Many of the coverings now on According to our invention, each strip or blank has a' marginal portion which is folded to produce a thick edge so as to present after set forth. The blank, while the coating or facing is softand plastic after its application to the impregnated foundation, or

after being rendered soft and plastic bythe application of heat, is folded or bent, so as to stretch and elongate the coating or facing at the line of the bend,V and is permitted to set oi harden while so stretched and elongated. IVhen this has been done, we find that the films of the wool felt or other iinpregnated foundation material are so stretched near one face and compacted near the other face, and the exposed facing so elongated,

that it is possible to move the doubled-over portion back and forth about the hinge so constituted, without the facing or coating breaking or cracking.

In Figli, we have shown conventionally the foundation (l impregnated with hydrocarbon or like saturating materia-l, and having coatings or facings b. The portion c has been bent back upon the. portion so`as to stretch the exposed coating at b and compact the coating b2. When the portion c is brought back into the plane of portion the coating at o separates from the body (taking with it some of the fiber, if thel foundation be of wool felt) without breaking or cracking.

As shown in Figs. l and 2, the two coat- Ings of the sheet or blank are differentlyy colored or tinted with suitable pigments so that they will contrast one with the other. Each sheet or blank is preferably formed with three hinges or fiexible portions (i, 7 and S. and is so bent back and forth as to -prov-.ide along one marginal portion four superimposed layers 9, 10, 11 and 12, (the layer 12 being formed by the body of the blank) whereby a thick exposed edge is provided. The marginal portion is so doubled back and forth upon itself that there are two double layers 9 and l0, and l1 and 12', with the lower double layer projecting ashort distance bevond the bend ofthe upper double layer. The extreme marginal portion 10, instead. of being folded under the portion 9, is preferablv folded over it,I

so that .a coating of one color is exposed thereby, and .a coating of a contrasting color or tint is exposed by the portions 11 and 12.

'The blanks as a whole are laid upon a roof or side wall with each blank overlapping` one or more blanks below it as shown. They are secured in place by nails or other fastenings which are passed through the three lower layers of each blank (and through the blank or blanks therebeneath) into the usual rigid wooden support 13, with the heads of the nails or fastenings subsequently Acovered by the body portion of the blank: The flexible hinge portions permit the body of the blank to be bent to expose the three lower layers 9, l0 and 11, for the driving of the nails therethrough, after which the body portion is positioned and thev next higher blank secured in place.

.Instead of having the lower layer or fold project beyond the upper layer orfold, they may register as shown in Fig. 3. By having the coating on' the under side of the blank darker in color orshade than that on the upper side, the appearance of solidity and thickness is greatly increased. I

In Figs. l to 3, the heads of the nails or fastenings 14 compress or compact the lower layers9, 10, 11, but it is evident that, while lthis is desirable, it is not essential. For instance, in Fig. 4, the extreme marginal portion 10 only is secured in place by the fastening, and in this case is doubled or folded under the portion 9, instead of over it as in Figs. l and 3. Inthis case, the natural resiliency of the covering causes the bends' or folds to tend to straighten and thus force the main body portion of the blank away from its support, thus greatly increasing the thicknessv of the exposed edge of the blank. It is evident that in theconstruction shown in Figs. l and 3 the extreme marginal portion 10 may be omitted, if desired, exposing the raw edge of portion 9, but, in any event, there are not less than three overlapping layers.

` ena roof or siding is laid as herein described, there is an appearance of thickness, with a marked shadow-effect produced by the greatly thickened edge. When narrow strips areyused on a side wall, the cov` ering presents a clapboard effect. The blanks may be in the form of shingles as well as in sheets or strips.

rThe blanks, in shingle form, may bev packed in stacks for shipment, or, if in sheet or strip forni, may be rolled. After the folds have been made and the stretched coating at the bends or hinges set, the sheet may be straightened laterally and wound longitudinally into a roll for shipment.

Having thus explained the nature of our said invention, and described a way of making and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, what we claim is:

1. A blank for forming roof or side coverings, consisting of a fiexible fibrous strip impregnated with waterproof material and coated 'with weatherproof material, said strip having along one edge narrow marginal portions folded back and forth, the

narrow folds lying one upon thel other to men, and comprlsing a body portion, and a marginal portion folded back and forth to expose not less than two closely adjacent folded edges, one below the other, said folded portions lying only 4under the margin of the blank.

4. A blank consisting of a flexible covering impregnated with waterproof material and coated on both sides with weatherproof pitch or bitumen of contrasting colors, and comprising a body portion and a marginal portion folded back and forth under the margin of the body portion to expose not less than two closely adjacent folded edges, the extreme marginal portion being folded inwardly over its adjacent layer, whereby the exposed edges expose coatings of different color.

In testimony whereof we have affixed our signatures, in presence of two witnesses.
